METAL FRAMING.

Application led April 27, 1928. Serial No. 273,304.

My invention relates to building construction and part-icularly to a novel metal frame arrangement for doors and similar wall openings.

An object of'my invention is to provide simple means for effect-ing a rigid connection between metal frame elements and a tile or other masonry wall. In construction heretofore suggested the metal frame has been held against lateral movement relative to a masonry wall by means of flat lugs or ears struck out from or welded to the sides of the metal members. The dat surfaces projected rearwardly of the frame, while performing the expected function of holding the frame relative to the wall, are objectionable in that plaster will not adhere thereto; and as the plaster is necessarily carried over the metal frame to the marginal edge thereof, there is a relatively large expanse of plaster that is unsupported by adherence.

To avoid this diliiculty and to prevent weakening of the frame mem er by striking out the lugs from the web thereof, I provide loops of wire that may be firmly welded to the sides of the frame member and that will perform the function of positioning and holding with certainty.

In addition, the construction described serves to greatly simplify the steps incident to the anchoring the frame elements against movement outwardly from the edge of the wall. rIhe anchoring device may directly engage the wire loops, and, if desired, may

o be formed permanently in place` thus positively assuring the anchoring of the frame member regardless of any skill or intention on the part of the workman.

The invention will be more readily understood by reference to the accompanying drawings, in which- Fig. l is a side elevation of a frame wire lug and anchor arrangement constructed in accordance with my invention;

Fig. 2 is a sectional view on line 2-2 of Fig. 1; i

Fig. 3 is an elevation from the rear of a modified form of the invention; and

Fig. 4 is a sectional view on line 4-4 of Fig. 3. l

In the drawings, and referring particularly to Figs. 1 and 2, I have illustrated a metal frame member of generally channel shape comprising a web 10, side flanges 11 and marginal flanges 12. The latter terminate in rebent portions 13 that constitute plaster anchors, and the angle of which, with the flanges 12, constitute a plaster ground. These frame members serve tooutline a wall opening and are adapted to receive wood or metal trip in the usual manner.

To the sides of the side flanges 11, I weld continuous lengths of wire bent into Zig- Zag form, thereby forming adjacent oppositely projecting loops of Wire. The loops 14 are welded to the sides of the flanges 11 While the loops 15 project beyond the edges thereof and constitute side stops for engagement with the sidesof the tile 16 or other forms of Walls.

Preferably the wires are bent to provide the straight portions 17 spaced at centers corresponding to the height of standard tiles; or if brick is used the straight portions will be so loca-ted that a joint in the brick will always come at some point in the extent of the stra-ight portions. To t-he straight portions of the wire is secured a cross wire 18 acting as an anchor. The wire constituting the anchor is preferably twisted around the straight portions 17, sufliciently loosely to enable the anchor to be moved up and down and while being shipped to he flat against the sides of the channel if desired. Preferably also the anchor will be curved or looped as shown in order to project the anchor portion as far as possible inwardly from the outer edge of the tile.

It Will be noted that by reason of this arrangement the workman cannot fail to anchor the frame members inasmuch as the anchor will be in his way unless he positions it as shown in the drawings.

In the modilied form shown in Figs. 3 and 4, the frame member is of integral form and comprises a sheet of metal bent to provide a jamb 19, a stop 20, molding 21-and plaster anchor 22. To the inner face of the jamb is welded at intervals the loops 23 of Wire having rearwardly extending projections 24 that function as means for laterally positioning the frame relative to the wall. The vertically extending portions of the loops are positioned. to overlie the `groove provided by forming the door stop, thus constituting a slot having a restricted opening adapted to receive an anchor 25 in the form of a flat strip having notches 26 in its sides and a T head 27 occupying the groove Within the stop.

The wireloops may be very simply formed complished by bending and applying' ivire" elements in other form-.sy than those,v illustrated and I do not Wish to be limited (exceptas indicated in the appended claims.

I claim:

1. In combination,A a steel `frame member and wires bent into loops and Weldedv te saidv raine member and havingportions/proL jecting rearwardly from said member to lie alongside of ar masonry Wall to hold the member against lateral movement relative to sai-d Wall. Y i

2. In combination, af steel ramemember and' Wires;Y bent into loops and Welded to said frame member and ha ing portions projeting rearwardly from sai-dz mem-ber to lie aloiigside of a masonry Wall to hold the member against lateral' movement relative tol said Wall, andh a Wall' anchor' engaging said wire loops.

3: in combination, aV metal I'rzune member and Wires-bentfinto" Zigzag fornr and secured tothe sides* of said' frame memberT portions of' the Wire projecting rearWafrdy lrom the frame' and' engaging the sides of masonry vvall'7 to serve as means for holding the frame against lateral movement relative to said wall.

Ll.x In combination, a metal frame member and Wires bent into zigzag `form and secured tothe sides of said frame member, portions of4 t'lievvire projecting rearwardly from the frame and engaging the sides of a masonry Wall, to serve as means for holding the frame against lateral movement relative to said Wall and a Wall anchor connected to said projecting portions.

5. In combination, a metal frame member and` Wires Welded to the said frame member and projectingrearwardly theretrom to aet as means for laterally holding the Yframe relative to awvall andan anchor permanentflj,v connected to saidivire members and adapted to lie' in the joints between courses of masonry constituting said Wall.

G. In combination, a metal frame mene ber and Wires Welded to the said iii-aine member and projecting rearwardly there from to act as a means for laterally holdingv the frame' relative to a` Wall andan anchor permanently connectedv to' said- Wire members and slidable relative thereto to lie between the course-s of masonry constituting said Wall. i
